We examined relationships between demographic and diagnostic variables and Benton Visual Retention Test performance in older adults aged 55 to 97 years. We derived extended geriatric norms for BVRT total number correct scores adjusted for variables that contributed significantly to the variance. We also investigated BVRT performance in two commonly(More)
The Standardized Luria-Nebraska Neuropsychological Test Battery was used for pre- and postoperative evaluation of two patients, each of whom had a large posterior parietal arteriovenous malformation (AVM) of the left cerebral hemisphere. In both cases the AVMs, which were fed by the left anterior, middle, and posterior cerebral arteries, were resected(More)
The relationship between size of cerebral ventricles in chronic schizophrenics and performance on a comprehensive neuropsychological battery, the Standardized Luria-Nebraska Neuropsychological Battery, was investigated. Ventricular size was determined by using a planimeter to measure the size of the lateral ventricles and the ventricular body, if present,(More)
This article investigates the adequacy of the Heaton-Grant-Matthews norms in correcting age and education effects in the Halstead Reitan Neuropsychological Battery. Two hundred and ninety neurological and 346 psychiatric patients were administered the Halstead Reitan Neuropsychological Battery. Raw scores were converted to standard scores using the(More)
Serum cortisol concentrations were measured after dexamethasone administration (1 mg) in 21 neuroleptic-free schizophrenic inpatients. Patients were assessed using the Brief Psychiatric Rating Scale and a battery of cognitive tests. A significant correlation was found between negative symptoms and both 8:00 AM and 4:00 PM post-dexamethasone cortisol(More)
Correlates of neuroleptic response latency were assessed in 16 male schizophrenic inpatients during 4 weeks of fixed dose (20 mg/day) haloperidol treatment. Rapid responders showed a mean 40% reduction in Brief Psychiatric Rating Scale (BPRS) positive symptom scores by day 10 of treatment. Rapid responders had significantly lower plasma homovanillic acid(More)
Experimental ischemia models have shown the antitussive dextromethorphan to be an N-methyl-D-aspartate antagonist with neuroprotective properties. We treated 10 patients with a history of recent stroke or transient ischemic attack with oral dextromethorphan (60 mg q.i.d.) for 3 weeks in a placebo-controlled, double-blind, crossover tolerance study. We(More)
Characterizing a pattern of cognitive dysfunction in early onset schizophrenic patients may illuminate neurodevelopmental contributions to the illness. A cohort of chronically institutionalized schizophrenic patients with a variable range of age of onset (range 7-29 years) was administered a comprehensive battery of neuropsychological tests that included(More)
Controversy continues regarding the differential diagnostic distinction between schizoaffective disorder and schizophrenia, and there are few published studies that examine the neuropsychological performance of schizoaffective patients. We evaluated 52 RDC-diagnosed schizophrenic and schizoaffective patients with equal numbers of medicated and unmedicated(More)
